The majority of creatures are invertebrates. Invertebrate animals are the major energy conduits and agents of nutrient and material recycling in marine, freshwater, and terrestrial ecosystems throughout the world, and the sustainability of the earth's life-support systems depends on theirwell-being. Despite this, conservation managers and practitioners still know very little about invertebrate biology, or how to study and survey invertebrates adequately in the field. Invertebrate Surveys for Conservation is a comprehensive guide to the ecological methods used to surveyinvertebrate animals in terrestrial, freshwater, and marine environments. It describes how to select particular taxonomic groups for study, how to collect and analyse samples, and how to set priorities for protection in the face of limited resources. Line drawings of apparatus, tables of surveyexamples and methods of specimen treatment and sample analysis are augmented by a substantial list of references to provide and introduction to practical invertebrate conservation. This book will be an essential tool for anyone involved in conservation biology or ecology, including students andresearchers, conservation practitioners, and environmental consultants.

This account explores how to promote biodiversity without compromising agricultural production in highly managed agricultural ecosystems.

This is an updated version of the best selling first edition, Ecological Census Techniques, with updating, some new chapters and authors. Almost all ecological and conservation work involves carrying out a census or survey. This practically focussed book describes how to plan a census, the practical details and shows with worked examples how to analyse the results. The first three chapters describe planning, sampling and the basic theory necessary for carrying out a census. In the subsequent chapters international experts describe the appropriate methods for counting plants, insects, fish, amphibians, reptiles, mammals and birds. As many censuses also relate the results to environmental variability, there is a chapter explaining the main methods. Finally, there is a list of the most common mistakes encountered when carrying out a census.

Invertebrate Conservation and Agricultural Ecosystems explores the diverse interests of invertebrate conservation and agricultural production. It is both an introduction to invertebrate conservation biology for agriculturists and an introduction to crop protection for conservation biologists, demonstrating how these two disparate fields may draw on each other for greater collective benefit. It draws on recent literature to show how invertebrate conservation in highly altered landscapes may be promoted and enhanced. The book deals with problems of, and approaches to, invertebrate conservation in highly managed agricultural ecosystems, and how biodiversity may be promoted without compromising agricultural production. It draws attention to the importance of invertebrates in agricultural systems and their role in ecosystem functions.

Studying invertebrates is a comprehensive guide to designing and carrying out ecological investigations, especially those involving sampling invertebrates. A highly practical guide to fieldwork, statistical testing and interpretation. The book introduces ways of designing and analysing experiments so that complex situations can be described and summarised, comparisons made, and interactions between organisms and their environment examined objectively. This digital reprint replaces ISBN 0-85546-313-9. First published in 2003. Editors' preface The books in this series are designed to encourage readers to undertake their own studies of natural history. Each one describes some relevant techniques, but they have not enough space to cover the substantial body of more generally applicable ideas and approaches that underlies the design and analysis of such field studies. By describing a selection of these general methods, Studying invertebrates aims to support those venturing into ecological fieldwork for the first time. The authors have plenty of experience in helping beginners to plan, carry out and interpret ecological surveys and experiments, and we hope this handbook will serve as a welcome companion and guide, especially for those who lack confidence in their knowledge of statistical and other methods.

The world's ecosystems are increasingly threatened by human development. Ecological impact assessment (EcIA) is used to predict and evaluate the impacts of development on ecosystems and their components,thereby providing the information needed to ensure that ecological issues are given full and proper consideration in development planning. Environmental impact assessment (EIA) has emerged as a key to sustainable development by integrating social, economic and environmental issues in many countries. EcIA has a major part to play as a component of EIA but also has other potential applications in environmental planning and management. Ecological Impact Assessment provides a comprehensive review of the EcIA process and summarizes the ecological theories and tools that can be used to understand, explain and evaluate the ecological consequences of development proposals. It is intended for the many individuals and companies involved in EIA and EcIA, as well as other areas of environmental management where impacts on ecosystems need to be evaluated. It will benefit planners, regulators, environmental consultants and scientists and will also provide an invaluable sourcebook and guide for the growing number of undergraduate students taking courses in applied ecology, EIA and related topics in environmental science. A practical management guide for the increasing numbers of practitioners of EcIA. A rapidly expanding subject driven by the proliferation of environmental legislation worldwide.
